when im at a stop light only once every so often it happens, and im stopped for like 10 sec. the truck will bump froward with brake pressed down??? has his happen to any one? kinda like it shift gears from park to drive but much stronger. tacoma 4.0 v6 prerunner

Mine started doing it the day I put my wheels and tires on, went from stock to 32 inch. I think it has something to do with changing the gear ratio due to new size tires and computer controlled shift points.

Mine does this sometimes, with the A/C off. It happens when I coast to a stop. I am sitting there when there is a sudden "lurch", almost feels like someone ran into the back of the truck very slowly. I drive an auto. I am starting to believe that when I coasted to a stop it stayed in second gear, then after a slight delay it engaged first and that it what I am feeling.

Haven't had to run the AC yet since getting my taco. I drove a standard for 7.5 years so the first time it did it i thought someone rolled up and hit me as well. But after it doing it a few times i think it comes from stopping to fast and the tranny catching up to slow? But jmo definately no taco experience here i've only had it for 2 months.
